El Niño Alert: Experts Warn of Potential 'Super El Niño' and Record Global Temperatures

Experts are closely monitoring climate patterns in the Pacific Ocean, which indicate a high chance of El Niño developing this summer. A strong El Niño event could lead to severe weather conditions, including super-charged rainstorms and droughts, depending on the region.

A 'super El Niño' could push 2027 to break global heat records, according to climate scientists. This phenomenon occurs when ocean surface temperatures in the central and eastern tropical Pacific Ocean warm up, leading to significant impacts on global weather patterns.

El Niño is characterized by warming of the ocean surface in the central and eastern tropical Pacific Ocean. It's one of three states scientists observe: La Niña, conversely, happens when sea surface temperatures are below average, and neutral conditions are defined when neither El Niño or La Niña are present and surface temperatures are about average.

The 'El Niño-southern oscillation' (Enso) tends to develop during spring in the northern hemisphere and shifts every three to seven years. Warming and cooling at sea surface during El Niño and La Niña can range from 1C to 3C, and have enormous effects on precipitation, drought, heat, and climate disasters in different regions.

Conditions are currently shifting from La Niña to a neutral pattern, according to the latest outlook from the US Climate Prediction Center. Models show a 62% chance El Niño will emerge this summer and linger until at least the end of the year.

A super El Niño that occurred in 2015 brought severe drought in Ethiopia, water supply shortages in Puerto Rico, and smashed records after unleashing a vicious hurricane season in the central North Pacific. A 'super' El Niño means one that is stronger, typically defined by sea surface temperatures spiking up to at least 2C.

Noaa scientists have given a 1 in 4 chance that this could happen by fall or winter, with the caveat that spring forecasts are sometimes muddled. Transitions in conditions that happen in the spring can make outcomes a bit harder to predict.

Experts warn that a strong or super El Niño could lead to drought and heat across Australia, southern and central Africa, India, and parts of South America. Heavy precipitation, meanwhile, could hit the southern tier of the US, parts of the Middle East, and south-central Asia.
